About silk waste

cpc code 39211 covers the industry of silk waste, which is a crucial component in the global textile and apparel supply chain. Silk waste refers to the byproducts and impurities generated during the silk production process, including cocoon floss, broken filaments, and other silk-based materials. This industry plays a vital role in the efficient utilization of silk resources, contributing to the sustainability and cost-effectiveness of the broader silk industry.

Production process

The production of silk waste involves the collection, sorting, and processing of various silk-based materials. Key steps include the harvesting of silk cocoons, the unwinding of silk filaments, and the separation of waste materials. These waste products are then cleaned, graded, and prepared for further processing or utilization in other industries.

Production inputs

The main inputs required for the silk waste industry include the raw silk cocoons and filaments generated during silk production. Additionally, specialized machinery and equipment, such as sorting machines and processing facilities, are necessary to handle and process the silk waste effectively. Labor and energy resources are also crucial inputs for the smooth operation of this industry.

Production outputs

The primary output of the silk waste industry is the processed silk waste material, which can be used in a variety of applications. This includes 39212 Silk yarn, 39213 Silk fabrics, and 39214 Silk garments, as well as other textile and non-textile industries that utilize silk-based materials. The efficient management and utilization of silk waste can contribute to the overall sustainability and profitability of the silk industry.
